Patented Sept. 12, 1939 arter tries Application July 2,1937, Serial No. 151,738 Renewed March 9, 1939 3 Claims.

By way of explanation, it may be stated that, when it is desired to mount a scaffold beam or putlog on a masonary wall, it has been the practice heretofore to leave an opening in the wall, to form a shoulder upon which one end of the beam may rest. Such an operation leaves a hole in the wall, to be filled later, causing patchwork which is unsightly.

lhe present invention aims to provide a novel support for the scaffold beam, the construction being such that the support may be introduced into the motar between courses, it being possible to remove the support, when the occasion for the use thereof has passed.

The invention aims, further, to provide novel means whereby the beam may be held on the support, and to supply novel means whereby the support will be held, by a mortar clinch, in the wall.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present inven tion appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrange ment of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 11 is a longitudinal section of the article appearing in Fig. 9;

Fig. 121s a longitudinal section showing a slight modification in the form illustrated in Fig. 9.

In carrying out the invention as disclosed in Figs. 1 to l, there is provided a support including an elongated plate I made of sheet metal of suificient strength to support the beam or" a scaffold. At its inner end, the plate I is tapered as shown at '2, so that it may be introduced readily into the mortar 3 between the courses i of a masonry wall In the tapered portion 2 of the plate I there is an opening IQ, of suficient size so that the mortar may engage in the opening, as shown at 54, thereby affording a temporary mortar clinch for holding the plate in place, the tapering oi the plate, at 2, facilitating the introduction of the plate into the mortar 3.

At the outer end of the plate 3 is located an upstanding, loop-shaped member, having an' opening l5 of sufficient size to receive the beam or putlog it of ascaffold, the upstanding member being designated as a whole by thenumeral 6. The upstanding member it has flanges '5 extended underneath the plate I and terminating closely adjacent to the longitudinal edges of the plate, the flanges i being secured to the plate by any suitable means, such as spot welding. If desired, the structure shown in Fig. 5 may be used, and therein the upstanding member 9 has its flanges 23 secured at their ends, as shown at H, by welding or otherwise, to the plate ill.

The beam I6 is inserted into the opening l5 of the loop-shaped member 6 and, in order to hold the beam against shifting endwise, securing elements l'l may be inserted into the beam 16, through openings it in the plate l. The openings l8 are somewhat smaller than the opening l2, and are located between the tapered portion 2 of the plate and the upstanding loop-shaped member 6.

It will be obvious that the device may be used to support the beam l6, without leaving large holes in the Wall 5. When the occasion for the use of the device has passed, it may be pulled out readily, and only a little pointing is necessary in order to close the opening in the mortar 3, formerly occupied by the inner end of the plate l.

The tapered end 2 of the plate l of one support may be inserted through the loop-shaped member 6 of another plate, and in this way, a plurality of the devices under discussion may be stacked in small compass, for transportation.

In Figs. 6, 7 and 8, the plate is marked by the numeral l9 and has a tapered inner end 20, in

fix a.

which is formed a hole 2| for the mortar clinch. The holes for the securing elements H of Fig. 2 are designated by the numeral 22. I

At its outer end, the plate l9 has a widened head 23 in which is formed an I-shaped slot 24, including a body 25 and extensions 26 at the ends of the body of the slot, the extensions being arranged at right angles to the body of the slot.

The head 23 of the plate is bent upwardly along the lines 21 at the rear ends of the extensions 26 of the slot 24, to form the side arms 28 of a loop-shaped member having an opening 29 for the reception of the scaffold beam. The end of the head 23 is bent along lines 39, located at the forward ends of the extensions 26 of the slot 24, to form a forwardly projecting wing 3i, and to form a rearwardly extended wing 32, the wings being located in the same plane, parallel to the plate [9. When the plate is turned up along the lines 21, to form the side arms 28, the part of the plate that is immediately behind the body 25 of the slot 24 remains in the same plane with the plate, to form a forwardly projecting tongue 33, located below the wing 3|, in parallel relation thereto.

In the form shown in Fig. 9, the blank of Fig. is used. The plate 34 has a tapered rear end 35, supplied with a large hole 36, to produce a mortar clinch. The holes for the securing elements are marked by the numeral 31. The broadened head of the plate is designated by the numeral 38 and has a rectangular opening 39. The head 38 may be turned up along the rear edge of the opening 39, to form a loop-shaped member 40, the opening 39 being available for the reception of one end of a beam.

In Fig. 12, parts hereinbefore described in connection with Figs. 9, 10 and 11 are designated by numerals previously used, with the suf- The modification of Fig. 12 consists in bending the upper part of the member 40a to form a wing 4|, which, like the wing 32 of Fig. 6, overlaps the beam.

In any of its forms, the device is simple in construction but will be found thoroughly advantageous for the ends in view.

If desired, the structure shown in Fig. 7 may be sold as an article of manufacture, the purchaser being left free to do the bending which produces the article shown in Fig. 6.

Having thus described the invention, what is claimed is:

1. A device for supporting a scaffold beam on a masonry wall, comprising a flat plate provided at its outer end with an integral upstanding member having a beam-receiving opening, the inner end of the plate being tapered for ready introduction into mortar, the tapered portion of the plate being provided with a first opening large enough to afiord a temporary mortar clinch for the plate, the plate being provided with a smaller opening for the reception of a beamengaging supporting element, the smaller opening being located between the upstanding memher and the tapered portion of the plate.

2. A device for supporting a scaffold beam on a masonry wall, comprising a plate provided at its outer end with an upstanding member having a beam-receiving opening, the upstanding member being provided with forwardly and rearwardly extended wings located at the upper edge of the opening and disposed approximately parallel to the plate, the plate being provided with a forwardly extended tongue prolonged beneath the forwardly extended wing, in approximately parallel relation thereto.

3. In a device of the class described, a plate having a tapered inner end for introduction into mortar, the plate being provided near to its outer end with an I-shaped slot including a body disposed transversely of the length of the plate, the slot including end extensions located approximately parallel to the length of the plate.
